Let's divide 728518 by 45
We want to figure out the number of times 728518 can be divided by 45.

Going ahead to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

On to step 2:
When dividing 72 by 45, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 72 and we're left with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 45

Advancing to step 3:
If we divide 278 by 45, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 8 after subtracting 270 from 278.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 45

On to step 4:
If we divide 85 by 45, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we subtract 45 from 85, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 45

On to step 5:
401 divided by 45 is 8 with a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 1618.0
If we subtract 360 from 401, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 45

Step 6:
45 goes into 418 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 16189.0
The remainder is 13 after subtracting 405 from 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 45 fits into 130 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 16189.2
The remainder is 40 after subtracting 90 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 45 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 16189.28
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 16189.288
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 16189.288 with a balance of 0.004.
